ong>Answer:

Present value of the car ( x ) = Rs3,45,000

Annually DECREASE of the value = d = 20%

Car VALUEAFTER 2 years

= present value × ( 100 - d)/100 × (100 - d )/100

= 345000× ( 100 - 20 )/100× ( 100 - 20 )/100

= ( 345000 × 80 × 80)/ ( 100 × 100 )

= Rs 2, 20,800

Value of the cat after 2 years = Rs 2,20,800

ong>Answer:

x(x - 2)= 1

x^2 - 2x - 1=0

Using splitting the middle term formula,

x^2 -(x+x) - 1 = 0

x(x - 1) + 1( x - 1) = 0

(x - 1)(x+1) = 0

x = 1 or -1

so, x^2+1/x^2= (-1)^2+1/(-1)^2

= 2/1

= 2

This is same for both the VALUES of x.

Hope you are satisfied with the answer.

8.5785× 10^30

Step-by-step explanation:

9.03× 10^30 - 45.15× 10^28

( at FIRST make the powers same)

= 9.03 ×10^ 30 - 0.4515× 10^ 30

then SOLVE by the method of subtraction of powers and EXPONENTS

= (9.03 - 0 .4515) × 10^30

= 8.5785×10^30.

Step-by-step EXPLANATION:

ong>ANSWER:

There are many rational numbers in between two numbers but here 3/5 is ALSO equal to 6/10.So there is no any rational number LIES between these two numbers.

by using identity- (a + b)²=a²+2ab+b²

⇒(100+8)²= (100)² + 2×100×8 + (8)²

⇒(100+8)²= 10000 + 1600 +64

ong>Given :  Model represents an equation. 2 long x tiles and 3 SQUARE 1 tiles = 3 long x tiles

To Find : Which represent like terms in the model of the equation?

SOLUTION:

2 long x tiles and 3 square 1 tiles = 3 long x tiles

2 long x tiles  

3 long x tiles

Represent like terms in the model of the equation

long x tiles  is common

and we can MAKE operation on their coefficients

We can subtract 2 long x tiles

from both sides

=>  3 square 1 tiles =   3 long x tiles  -  2 long x tiles

=>   3 square 1 tiles = 1 long x tile

Please Mark As Brainliest

Step-by-step explanation:

Roohi travels 300 km to her home partly by train and partly by bus. She takes 4 hours if she travels 60 km by train and the remaining by bus. If she travels 100 km by train and the remaining by bus, she takes 10 minutes longer. Find the speed of the train and the bus separately.

Share

Study later

ANSWER

LET the speed of the train be x km/hr and the speed of the bus is y km/hr.

So according to QUESTION and USING Time=

Speed

Distance

Total distance =300 km

Roohi travels 60 km by train and 300−60=240 by bus in 4 minute,

x

60

+

y

240

=4

and 100 km by train, 300−100=200 by bus, and takes 10 minutes more,

x

100

+

y

200

=4+

60

10

⇒

x

100

+

y

200

=

6

25

Now, let

x

1

=u and

y

1

=v

then 60u+240v=4.............eq1

100u+200v=

6

25

..............eq2

multiply eq1 by 5 and eq2 by 6 we get

300u+1200v=20..........eq3

600u+1200v=25...........eq4

Subtracting eq3 QND eq4 we get

−300u=−5

u=

300

5

=

60

1

Putting the value of u in eq1 we get

60×

60

1

+240v=4

240v=3

v=

240

3

=

80

1

Now

x

1

=u=

60

1

∴x=60

and

y

1

=v=

80

1

∴y=80

Hence the speed of the train is 60 km/hr and the speed of the bus is 80 km/hr.

ong>ANSWER:

x² + 2x - 360=0

real and distinct roots

Step-by-step EXPLANATION:

dividend = divisor*quotient +remainder

let divisor be x,

then quotient = 2x+4

=>729 = (2x+4)x +9

=>729= 2x² +4X +9

=> 2x²+4x-720 = 0

=> x² + 2x - 360=0

=> x² -18x+20x-360=0

=> x(x-18)+20(x-18) =0

=> (x-18) (x+20)=0

roota are 18,-20

real and distinct roots

ong>Answer:

You call an expression with a single term a monomial, an expression with TWO TERMS is a binomial, and an expression with three terms is a trinomial. An expression with more than three terms is named simply by its NUMBER of terms. For example a polynomial with five terms is called a five-term polynomial.
